2 DR. series AC motorsGeneral Product Description

2 General Product Description2.1 DR. series AC motorsNoise The noise levels of all motors from SEW-EURODRIVE are well within the maximum per-

mitted noise levels set forth in IEC/EN 60034-9.

CoatingDR motors The DR motors are painted with "blue/gray" machine paint RAL 7031 as per DIN 1843

as standard. The asynchronous servomotors of the DRL series are also available in"black" machine paint, RAL 9005 as per DIN 1843, at no extra cost. Special coatingsand other colors are available on request.

Surface and corrosion protectionIf required, all motors from SEW-EURODRIVE can also be supplied with special surfaceprotection for applications in extremely humid and chemically aggressive environments.

Air admission and accessibilityThe motors / brakemotors must be mounted on the driven machine in such a way thatboth axially and radially there is enough space left for unimpeded air admission and formaintenance of the brake. Please also refer to the notes in the motor dimension sheets.

Brakemotors On request, the motors can be supplied with an integrated mechanical brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil that releases elec-trically and brakes using spring force. Due to its operating principle, the brake is appliedif the power fails. It meets the basic safety requirements. The brake can also be releasedmechanically if equipped with manual brake release. For this purpose, the brake is sup-plied with either a hand lever with automatic reset or an adjustable setscrew. The brakeis controlled by a brake controller that is either installed in the motor wiring space or thecontrol cabinet.A characteristic feature of the brakes is their very short design. The brake bearing endshield is a part of both the motor and the brake. The integrated construction of the SEW-EURODRIVE brakemotor permits particularly compact and sturdy solutions.

Inverter operation DRS/DRE/DRP motors can be combined with the proven SEW-EURODRIVE frequencyinverter series MOVIDRIVE®, MOVITRAC®, MOVIFIT® and MOVIMOT®, and as of nowalso with MOVIPRO®.The asynchronous DRL servomotors are operated with the inverters of theMOVIDRIVE® series and the multi-axis servo inverters of the MOVIAXIS® series.

International marketsOn request, SEW-EURODRIVE supplies UL registered motors or CSA certified motorswith connection conditions according to CSA and NEMA standard.For the Japanese market, SEW-EURODRIVE offers motors conforming to JIS standard.Contact your sales representative to assist you in such cases.

Energy-efficient motors of the DR motor seriesGeneral Product Description

2.2 Energy-efficient motors of the DR motor seriesSEW energy-efficient motors tap the full potential

Since 2002, SEW-EURODRIVE has been using rotors with a cast copper cage for theproduction of energy-efficient motors.The advantages of this innovative copper die-cast technology used for the DR motor se-ries is beneficial to the entire motor spectrum.The design, which is optimized in size and material, allows for combining standard mo-tors, energy-efficient motors and premium motors in one series for the first time. This means that using different motor types or series is a thing of the past as well asusing different additional features and options.

In view of existing and foreseeable national and international legislation and regulations,the DR motors have been developed and designed as a modular energy saving system.They apply all the advantages of a modular system with re-usage and multiple usage ofparts to achieve the required efficiency levels safely and easily.

Voluntary agreementCEMEP, the association of European electric motor manufacturers, has reached anagreement with the European Commission’s General Directorate for Energy that all 2and 4-pole low-voltage AC motors from 1 to 100 kW will be classified on the basis oftheir efficiency, and that this classification will be identified on the nameplate and in cat-alogs. The classification distinguishes between EFF3, EFF2 and EFF1 classes. EFF3 refers to motors without any particular efficiency requirement. EFF2 indicates im-proved efficiency motors and EFF1 is for high-efficiency motors.Since 1997, SEW-EURODRIVE has participated in creating the voluntary agreement.We actively advocated an extension of the voluntary agreement in 2005, and we coun-tersigned the agreement in 2006.The efficiency values are determined according to the method described in IEC 60034T2 (1972), assuming 0.5 % additional losses.

EFF2 The DRS AC motors of sizes 80M to 225MC meet the requirements of efficiency classEFF2.

EFF1 The DRE AC motors of sizes 90M to 225MC meet the requirements of efficiency classEFF1.

Premium The voluntary agreement from 1998 does not include any premium class motors yet.The 4-pole DRP AC motors of sizes 90M to 225MC surpass the requirements of efficien-cy class EFF1 significantly.This means they are energy-efficient motors of the Premium efficiency class. The European manufacturers of asynchronous AC motors agreed to stop labeling themotors according to the Voluntary Agreement in spring 2009, and to classify them in-stead according to IEC 60034-30 with IE1, IE2 and IE3.


2 Energy-efficient motors of the DR motor seriesGeneral Product Description

EuP directive The European Commission enacted a directive in 2005 which contains regulations con-cerning the permitted energy consumption of products. Lot 11 of the directive2005/32/EC - Energy Using Products - also includes asynchronous AC motors.After the publication of the results of a study by order of the EU commission about thebest possible design of asynchronous AC motors, implementing regulations were drawnup in winter 2008/2009 in Brussels.They prohibit the sale of motors with standard efficiency levels and stipulate a minimumefficiency equivalent to IE2 as of June 16, 2011. Two more stages for increasing theminimum efficiency levels of asynchronous AC motors to the Premium level were deter-mined as well. As of January 2015, motors with a power rating of 7.5 kW and higher will have to meetlevel IE3, and as of January 1, 2017, motors with a power rating of 0.75 kW and highermust meet level IE3 in supply system operation. Motors of class IE2 operated on a fre-quency inverter are exempt from this.The implementing regulation for the EuP directive refers to the new parts of IEC 60034.In part T30 (see below), the international classification and minimum efficiency valuesare described. The new T2-1 part regulates the method for determining the numericalvalue of the efficiency.The DRE and DRP energy-efficiency motors comply with the specifications and valuesderived from IEC 60034 2-1 and -30.The motors are no longer labeled with the EFF1 logo.

IEC 60034 T2-1 (2007)Part 2-1 of IEC 60034 still describes the measuring method for determining the efficien-cy of an asynchronous AC motor. What is new in part 2-1 is how additional losses are determined. The across-the-boardapproach of 0.5% is no longer used. A power-based value of 3.5% for small power rat-ings down to 0.5% for large motors has replaced it.These numbers seem to indicate that the motor performance has worsened, eventhough only the across-the-board proportion was changed. No motor component wasmodified and the energy consumption is still the same.

IEC 60034 T30After different standards have coexisted for years, part 30 of IEC 60034 now constitutesan internationally uniform efficiency classification. Similar to the IP label for the degree of protection, this classification will be based on IE.The abbreviation IE stands for "International Efficiency".Currently, there are three classes:• IE1= Standard Efficiency = EFF2• IE2= High Efficiency = EFF1• IE3= Premium EfficiencyMinimum efficiency levels are defined for classes IE1, IE2 and IE3 at 50 Hz and at 60Hz, 2-, 4- and 6-pole, in the power range 0.75 kW to 375 kW. This is the first time sucha standard is available for consumers, manufacturers and legislature.

Energy-efficient motors of the DR motor seriesGeneral Product Description

The values for the efficiency levels in accordance with IEC 60034-30 are listed in thetechnical data overview for DRS, DRE or DRP motors (see page 44 ff).

MEPS 2006 The minimum efficiency (MESP) stipulated by law both in Australia and New Zealandhas come into effect on April 1, 2006 in Australia and on June 1, 2006 in New Zealand.It regulates numerical values and measuring methods for the efficiency of 2-, 4-, 6- and8-pole motors from 0.75 kW (1 hp) to 185 kW (250 hp).There are no regulations up to 0.55 kW; the DRS motors up to this power rating aretherefore permitted.For 0.75 kW and higher, the specified efficiency values correspond to those of the Eu-ropean EFF1 motors.The DRE motors and the advanced DRP motors meet the legal requirements and havebeen approved by the authorization agency.Indivisible gearmotors are exempt from the regulations. SPIROPLAN® W30 gearmotors(also WA30, WF30, WAF30) and R17 helical gearmotors (also RF17, RZ17) with motorsfrom 0.75 kW to 1.1 kW in DRS design can therefore be supplied in line with the regu-lations.For an overview of permitted motors on the Internet, go tohttp://www.energyrating.gov.au/appsearch/motors.asp and select SEW-EURODRIVE.

USA, CanadaRegistering AC motors with UL (Underwriters Laboratories) offers advantages for theUS-American market, since this ensures a lower fire insurance premium.For the Canadian market, a CSA (Canadian Standard Association) approval is manda-tory.The motors of the DR series have the following approvals:• UL (as recognized component UR) and• CSA.

DRS motors This means the following designs of 4-pole DRS motors can be supplied to the USA andCanada.

Asynchronous servomotors of the DRL seriesGeneral Product Description

People’s Republic of China

Asynchronous AC motors delivered to China must comply with minimum efficiency reg-ulation that became effective on January 18, 2008.Until July 1, 20011, a motor of class EFF2/IE1 is sufficient. After that, the motor must bein class EFF1/IE2.As the motors must be labeled accordingly, we ask you to specify this when orderingDRE motors for delivery to China.Approval of the DR motors is pending. Please contact your SEW-EURODRIVE repre-sentative for additional information.

2.3 Asynchronous servomotors of the DRL seriesAsynchronous servomotors are the link between the classical asynchronous AC motorsfor supply system and inverter operation and the highly dynamic synchronous servomo-tors with permanent magnets.

DRL motors Asynchronous servomotors of the DRL series are a drive package made up from themany options of the modular DR motor system.In its basic variant, the drive package always contains• Encoder, sine signals and electronic nameplate,• Thermal motor protection• Dynamics package• Various connection options• Winding optimized with respect to speedDepending on the application· and requirements, the following elements can be added:• Forced cooling fan• Connection via plug connectors instead of terminals• Temperature sensing• And many moreAlternatives can be selected instead of the elements of the basic variant, e.g. an abso-lute encoder instead of the sine encoder.


2 Asynchronous servomotors of the DRL seriesGeneral Product Description

Dynamics AC motors operated on the supply system usually have an overload capacity of 160% –180% of the rated torque during startup.If the motor is operated on an inverter of the same power, the inverter usually provides150% current, and thus roughly 150% torque, for 60 seconds during startup. If a largerinverter is selected, the inverter can provide a higher current and theoretically a greatertorque as well. In this case, the mechanical resistance of the motor against the overload,which might reach or exceed the permitted limit values, must be checked.As a rule, the synchronous servomotors and the corresponding inverters are designedfor a high short-time overload. 400% of the rated torque can usually be reached and arepermitted.The mechanical design of asynchronous servomotors of the DRL series is of such a highquality that dynamic overload values can be reached which exceed the classical valuesof an asynchronous motor operated on a supply system or inverter and almost matchthe values of a synchronous servomotor.SEW-EURODRIVE offers the DRL motors in two dynamics packages:

The nameplate of the motor specifies the respective dynamics package.

Speeds SEW-EURODRIVE offers the DRL servomotors with 4 rated speeds:• 1200 rpm• 1700 rpm• 2100 rpm• 3000 rpmIn inverter operation, field weakening begins at the rated speed.

Package Overload capacity to rated torque

Dynamics 1 (D1) 190 % - 220 %

Dynamics 2 (D2) 300 % - 350 %

Switching and protective equipment of the DR motor seriesGeneral Project Planning Notes

In the tolerance range A, the motor must be able to deliver the rated torque in continuousduty (S1). The other characteristic values and the heat development may deviate slightlyfrom the rated voltage and rated frequency values.In the tolerance range B, the motor must be able to deliver the rated torque but not incontinuous duty. The increase in temperature and deviations from the rated data arehigher than in tolerance range A. Avoid frequent operation of the motor at the limits oftolerance range B.

Undervoltage It is not possible to achieve the values in the catalog such as power, torque and speedin the event of undervoltage due to weak supply systems or an insufficiently large motorcable. This is particularly true for motor startup where the starting current amounts to amultiple of the rated current.

3.2 Switching and protective equipment of the DR motor seriesEMC measures AC motors, AC brakemotors and MOVIMOT® drives from SEW-EURODRIVE are com-

ponents for installation in machinery and systems. The designer of the machine or sys-tem is responsible for complying with the EMC directive 2004/108/EC. Please refer tothe publication "Drive Engineering - Practical Implementation, EMC in Drive Engineer-ing" for detailed information about this topic. For specific information on MOVIMOT®

drives, refer to the "Drive System for Decentralized Installation" system manual.

Supply system operation

SEW-EURODRIVE AC (brake) motors satisfy the EMC generic standards EN 50081and EN 50082 when used in accordance with their designated use in continuous supplysystem operation.

Switching opera-tion

For switching operation of the motor, take suitable measures for suppressing interfer-ence from the switchgear.

Inverter operation For inverter operation, refer to the installation and EMC instructions provided by the in-verter manufacturer.Please also note the information in section "Operation on inverters" on page 100 ff andthe following project planning guidelines:

Brakemotors on the inverter

Install the brake cables of brakemotors separately from the other power cables, main-taining a distance of at least 200 mm. Joint installation is only permitted if either thebrake cable or the power cable is shielded.

Connecting tachometers to inverters

Observe the following instructions when connecting the tachometer:• Use a shielded cable with twisted pair conductors only.• Connect the shield to the PE potential on both ends over a large surface area.• Install signal cables separately from power cables or brake cables (min. distance 200

mm).Please also note the information in section "Operation on inverters" on page 100 ff .

Connecting posi-tive temperature coefficient thermis-tor (TF) to the inverter

Install the connecting lead of the positive temperature coefficient (PTC) thermistor TFseparately from other power cables, maintaining a distance of at least 200 mm. Collec-tive installation is only permitted if either the TF cable or the power cable is shielded.


3 Switching and protective equipment of the DR motor seriesGeneral Project Planning Notes

Motor protection Selecting the correct protection device is a significant factor in determining the opera-tional reliability of the motor. We distinguish between protection devices that are current-dependent and those that depend on the motor temperature. Current-dependent protec-tion devices include fuses or motor circuit breakers. Temperature dependent protection devices are PTC thermistors or bimetallic switches(thermostats) in the winding. PTC thermistors or bimetallic switches respond when themaximum permitted winding temperature is reached. The advantage is that tempera-tures are measures where they actually occur.

Motor circuit break-ers

Motor circuit breakers offer adequate protection against overload in standard operationwith a low switching frequency, brief start-ups and starting currents that are not exces-sive. The motor circuit breaker is set to the rated motor current.Motor circuit breakers are not adequate as the sole means of protection given switchingoperation with a high switching frequency (> 60 per h) and for high inertia starting. Inthese cases, SEW-EURODRIVE recommends to use positive temperature coefficientthermistors TF in addition.

TF PTC thermistor Three positive temperature coefficient thermistors TF (PTC, characteristic curve accord-ing to DIN 44080) are connected in series in the motor and connected from the terminalbox to the TF/TH input of the inverter or to a trip switch in the control cabinet. Motor pro-tection with positive temperature coefficient (PTC) thermistors TF provide comprehen-sive protection against thermal overload. Motors protected in this way can be used forhigh inertia starting, switching and braking operation as well as with fluctuating powersupply systems. A motor circuit breaker is usually installed in addition to the TF. SEW-EURODRIVE recommends always using motors equipped with TF for inverter opera-tion.

TH bi-metallic switch

Three bimetallic switches TH, connected in series in the motor, are looped directly intothe motor monitoring circuit from the terminal box.

Trigger tempera-ture

Thermal motor protection is realized by TF temperature sensors or TH bimetallic switch-es built into the end winding of the motors. The trigger temperature is slightly lower thanthe limit value of the thermal classification to achieve maximum motor protection. Tem-perature sensor TF and bimetallic switch TH are available with the following trigger tem-peratures:

Switching and protective equipment of the DR motor seriesGeneral Project Planning Notes

KTY temperature sensor

KTY temperature sensors are used to determine the temperature at the installation lo-cation and is usually measured in the winding.For modern, highly dynamic inverter drives, the temperature of the motor model storedin the inverter (procedure similar to CFC) is corrected to achieve higher dynamic prop-erties. In this case, it is necessary to detect the winding temperature, e.g. with KTY sen-sors.

Fuses Fuses do not protect the motor from overload. Their only purpose is short-circuit protec-tion.

Various protection equipment

The following tables show the qualification of the various protection devices for differentcauses of tripping.

Secure switching of inductancesNote the following notes for switching of inductances:

Switching of motor windings with a high number of poles

If the cable is installed unfavorably, switching of low-speed motor windings can generatevoltage peaks. Voltage peaks can damage windings and contacts. Install varistors in theincoming cable to avoid such problems.

Switching of brake coils

Varistors must be used to avoid harmful switching overvoltages caused by switching op-erations in the DC circuit of disk brakes.Brake control systems from SEW-EURODRIVE are equipped with varistors as standard.Use contactors with contacts in utilization category AC3 or better to EN 60947-4-1 forswitching of brake coils.

Suppressor circuit on the switching devices

According to EN 60204 (Electrical Equipment of Machines), motor windings must beequipped with interference suppression to protect the numerical or programmable logiccontrollers. Because problems are primarily caused by switching operations, we recom-mend installing suppressor circuits on the switching devices.

Unit designations for the DR. motor seriesUnit designations

Output types of the motors

Foot-mounted motor

Unit designation /FI SEW motor with IEC feet and A endshield

Description The /FI foot-mounted motor is designed as a motor with a shaft end and feet to IEC spec-ifications. The shaft and feet dimensions for 4-pole motors are based on the power ratingof the DRS motor.Different feet and shaft dimensions are available for motors with efficiency rating re-quirements (DRE, DRP).According to EN50347, each power rating is assigned the corresponding shaft height.Some DR motors allow for implementing a higher power rating in a smaller size (e.g.DRS100LC4 with 4 kW). If an application requires the EN compliant shaft height, the motor can be equipped withanother foot height instead.If the power assigned to the motor differs from EN50347, the shaft height will be indicat-ed in the unit designation. For example: DRS100LC4/FI112M.

7 series gearmotor

Unit designation /FGMotors for gear unit mounting

Description Motors sold as stand-alone motor with preparation for mounting to a gear unit are as-signed the designation /FG. This designation is eliminated if the motor is mounted to-gether with the gear unit (as conventional gearmotor).The /FG flange mounted motor is the gear unit mounting version of the motor. The flangedimensions are implemented according to the SEW work standards for gear unit mount-ing.The pinion shaft end is dimensioned according to the motor power rating. It is thereforepossible that DRS, DRE and DRP motors have different pinion shaft ends within onemotor size and length.

Description The design /FF is a variant with through bores in the flange, comparable to IEC type ofconstruction B5.The flange dimensions for 4-pole motors with Standard Efficiency (DRS), High Efficien-cy (DRE) or Premium Efficiency (DRP) are based on the power rating according to thestandard.Flange combinations deviating from the standard are given the unit designation /FL (seebelow).If the motor size deviates from the standard, the flange size is added accordingly: e.g.:DRS90L4/FF100M



IEC flange-mounted motor with threads

Unit designation /FTIEC flange motor with threads

Description This type is for example comparable with the IEC type B14. The flange dimensions for shaft dimensions of 4-pole motors with standard efficiencylevel (DRS) are designed according to the standard EN 50 347 2001.Other shaft dimensions are available for energy-efficient motors or for power enhancedmotors with copper rotor.

Flange-mounted motor (deviating from IEC)

Unit designation /FLFlange-mounted motor with dimensions deviating from IEC

Description This flange-mounted motor is a motor variant deviating from IEC.The /FL option enables the customer to choose an IEC flange that does not correspondto the power assigned to the motor (see IEC standard flange assignment /FF).The shaft collar is not necessarily at the same level as the flange bolt surface.

"C-face" flange-mounted motor

Unit designation /FC

Description The "C-face" flange-mounted motor is a motor type with tapped holes in the flanged endshield similar to an FT type (B14).The flange and shaft dimensions for 4-pole DRS motors with standard efficiency levelare designed in compliance with the NEMA standard (in inches).

7 series gearmotor with feet

Unit designation /FMIntegral motor on 7 series with feetOnly motors sold as stand-alone motors with preparation for being mounted to a gearunit are assigned the designation /FM. This designation is eliminated if the motor ismounted together with the gear unit.

Description /FM is the gear unit mounting version of the motor with feet. It is the combination of theoptions /FG and /FI.The flange dimensions are implemented according to the SEW work standards for gearunit mounting.The pinion shaft end is dimensioned according to the motor power rating. It is thereforepossible that DRS, DRE and DRP motors have different pinion shaft ends within onemotor size and length.
